Full list of radio locations?[edit]
So far I've found two further radios that are not listed here. There were two radios in Chamber 15; one at the beginning of the level and one at the end. I've also just found another in a room inside an air duct with a makeshift bed and some supplies, which I guess would be the "Escape Part 2" bit that's not on the list. I'll keep looking. 115.64.118.162 12:18, 20 March 2010 (UTC)
Your description of the transmission location for the first radio in chamber 18 is woefully inadequate. What Notch? Where? and "Right" is relative. What way are you facing? To your right as you exit Ratman's lair, facing the next platform? I see a height transition between two portable-able ceilings, but no "notch" - You might also mention that you need to crouch to hold the radio through a floor portal without dropping it. RedwoodElf
I can't find more radios than the one in Chamber 00[edit]
I have found a radio - Chamber 00 - and brought it into the button room, as you said. However there was no red/green light. Instead it was blue. Also - in chamber 01 - there is NO radio on top of the camera - or am I wrong? —The preceding unsigned comment was added by 93.199.69.110 (talk • contribs) 06:01, 15 December 2010.
- If you can't find a radio on most of the maps, then you probably have an older version of Portal. --Sigma 7 23:14, 17 December 2010 (CST)
Is this achivement avalible for the xbox[edit]
Can I get these radios on xbox or is it 100% only steam...
- If the Xbox achievement, radios, or green/red radio led aren't visible, then your version doesn't have it. --Sigma 7 03:42, 19 May 2011 (UTC)
Revamping/rewording in progress[edit]
That. Created a third column to separate the ideas of getting the radio and delivering the radio to the location. I have adjusted descriptions for this achievement in chambers up to 10, as that's as far as I've gotten in adjusting the guide so far. I plan on getting the rest soon. Let me know if you have general wording suggestions for the first half of the table, as currently it is sometimes mixing sentence fragments (due to the column title being the subject of the "sentence") with complete sentences that further describe how to get/deliver the radio. -- Ceegers (talk) 04:23, 26 July 2012 (UTC)
